I'm not blaming the websites, but as we all know that cloud mining platforms are about 99% scams and they can never be trusted with money, so it is better to see all the possible ways they can use to lure more users.
Yeah I do agree with you back couple years ago Hashnest is the official product of Bitmain the others like Antpool and Antminer is a well-known brand but after I hiatus couple of years the site is dead They should be a profitable company at least the first is like that.
Long story short I found Company that backed by bitmain called Bitfufu and there is news about it https://www.bitfufu.com/news/NEW100019 - https://www.prnewswire.com/news-releases/bitmain-backed-bitfufu-finfront-holding-company-a-world-leading-digital-assets-cloud-mining-service-provider-entered-into-a-definitive-merger-agreement-with-arisz-acquisition-corp-301467547.html?tc=eml_cleartime
If you are a new member of course will fall like to this even me but they asked KYC for the first time so I think is probably shit just like Hasnest
